Excess oil is one of the leading causes of acne. Effective oil control begins with proper cleansing. A targeted acne cleanser removes surface oil and impurities while helping regulate sebum production throughout the day. This reduces shine, congestion, and the formation of blackheads and whiteheads. Regular cleansing also prevents buildup from sunscreen, makeup, and pollution, which can clog pores if left untreated. For people with oily skin, skipping cleansing or using unsuitable products often leads to increased breakouts. A well-balanced routine keeps pores clear without disrupting the skin barrier.
